Driver forced fullscreen AA is working for me, it makes hard edges smooth, but shows artifacts on planets with atmospheres. I haven't worked on anti-aliasing very much, I will return to it in a future version.

Driver forced AA also does not work for me. I have tried both widowed and fullscreen with UseDesktopSettings both true and false. FXAA works for me, but it does not produce the same quality as normal AA and it also affects HUD text
